Description
Technical field
The present invention relates to electric energy meter, relate in particular to a kind of calibration equipment and method thereof of prepayment IC-card electric energy meter.
Background technology
For reducing the waste of human and material resources in the electric energy toll administration, solve the problem of electric company's difficult charge, for the foundation of charging accurately is provided between electricity consumption user and the electric company, the prepayment IC-card electric energy meter that have higher reliability, scientifically calculates power consumption has obtained popularization energetically.
Chinese patent: " full electronic prepayment IC-card electric energy meter (CN2289247Y) ", comprise power converting circuit, current sample and voltage sampling circuit, analog multiplier, V/F transducer, multistage counter, meter degree display adds up, electric energy meter checking device, single chip microcomputer computing machine, surplus electric demonstration and warning, IC-card input, data access, the control circuit of operating a switch.The IC-card electric energy meter has overcome the defective of stem-winder, the reliability height.In Chinese patent, also disclosed the method for inspection of electric energy meter, Chinese patent: " the single-phase pre-payment electric energy meter verifying attachment and the method for inspection thereof (CN101477726) ", device comprises control system, program control single-phase power source, the single-phase multifunctional standard scale, Error Calculation/display and electric energy meter meter hanging frame, tested electric energy meter is arranged on the electric energy meter meter hanging frame, this device includes the pre paid functionality tentative module, pre paid functionality is connected in parallel on and is connected on the tested electric energy meter electric current end word, when carrying out the test of single-phase pre-payment electric energy meter pre paid functionality, guarantee that in the single-phase pre-payment electric energy meter tripping operation with when closing a floodgate power source can operate as normal by the pre paid functionality tentative module.
In the process of the production verification of prepayment IC-card electric energy meter in batch process, the method for inspection exists obviously not enough.The conventional method of inspection is: device provides working power, selects corresponding IC-card for use according to the concrete function of test then, and whether this function card of plug and artificial judgment Card Reader be successful in every IC-card table successively.So the frequent card that manually plugs and unplugs has repeatedly brought very big inconvenience to verification, the subject matter of routine inspection method has:
1, security reduces: have certain security risk in the management that verification also blocks after with the card drawing before each verification of various function IC-cards, verification;
2, inefficiency: thereby because the artificial frequent IC-card that plugs and unplugs has reduced work efficiency, and have the possibility of artificial misplug card;
3, automatization level is low: because the existence of artificial plug-in card, thereby cause accomplishing full-automatic verification.
